12. A fluid is flowing through a pipe with a radius of 5.1 x 10-3 m. The viscosity of the fluid is 1.0 x 10-3 Pa-s. A flow rate of 2.8 x 10-4 m3/s is required, and it is found that a pressure difference of 1.8 × 103 Pa is needed to drive this flow. With this information, calculate the length of the pipe. Hint: assume the flow is viscous flow (a) 1.7 m (b) 5.9 m (c) 3.2 cm...
Below are typical values for blood flow through a coronary artery. Note that viscosity of the blood is not neglected. Density of blood, ρ = 1060 kg/m3 Viscosity of blood, ν = 0.004 Pa x s Flow rate, Q = 0.8 mL/s Length of artery, L = 3.5 cm Radius of artery, r = 0.2 cm For the same pressure drop, calculate the flow rate if the radius of the artery reduces by 30% its original value due to blockage?

A flow nozzle equipped with a differential pressure gage is used to measure the flow rate of water at 10°C (p 9997 kg/m3 and p 1.307 x 10-3 kg/m s) through a 3-cm-diameter horizontal pipe. The nozzle exit diameter is 1.5 cm, and the measured pressure drop is 3.3 kPa. Determine the volume flow rate of water, the average velocity through the pipe, and the head loss 1.5 cm Differential pressure gage -3 m3(s m/s The volume flow rate of...
If a constriction occurs in a vein or artery, the heart will have to work considerably harder in order to produce a higher pressure drop and hence maintain the required blood flow rate. The diameter of a person’s left anterior descending artery has decreased by 10% due to arterial sclerosis. If the amount of blood pumped through this artery per unit time is the same as before the constriction developed, by what factor has the blood pressure drop (from one...
In the normal region of an artery, the blood pressure is 100 mm Hg and the flow speed is 0.12m/s. By what percentage would the pressure drop in this artery as the blood (density 1.05 x 10^3 kg/m^3) enters a region that has been narrowed by atherosclerotic plaque to a cross-sectional area one fifth of normal? Assume there is no change in elevation of artery and viscosity is negligible
